Stone foundation inspection, diagnosis, repair: this article explains Stone Foundations & Walls: How to Recognize & Diagnose Stone Foundation Cracks, Bulges, Movement, or other Stone Wall Damage such as damage due to impact, settlement, frost or water damage, and other causes. Types of foundation cracks, crack patterns, differences in the meaning of cracks in different foundation materials, site conditions, building history, and other evidence of building movement and damage are described to assist in recognizing foundation defects and to help the inspector separate cosmetic or low-risk conditions from those likely to be important and potentially costly to repair.

Stone foundation walls on pre-1900 buildings are often quite thick, up to four feet at their base. In their original design these walls tolerated water in the outside soils by permitting it to seep through the wall and often to drain away through a dirt floor or even a through-wall drain in a low corner. Such dry-laid structural stone foundation walls rarely fail by leaning but are often found bulged or damaged by water, frost, vehicle traffic, or by modification by the building owner.
Some common stone foundation wall or stone structural wall defects to be observed and reported include:
